12 Volts Voltage Regulator Car Adapter

A simple 12 volts voltage regulator car adapter circuit can be used to power your electronic devices from your car can be designed using few common electronic components.

12 Volts Voltage Regulator Car Adapter Circuit Diagram:

This 12 volts voltage regulator car adapter circuit use a 12.7 volts zener diode but maybe you can’t find a 12,7 volts zener , so in that case you can use a 12 v or 13 volts zener diode . If you will use a 12 volts zener you will need to stick in another diode like 1N4001 (in this case the output voltage will be a little under 12 ) and if you will use a 13 volts zener the output voltage will be around 12.3 volts.
